Talk:Multi-core processor

I agree with the merge proposal. TechPurism 00:42, 27 December 2005 (UTC)[reply]

Defragmenting and antivirus are not CPU intensive operations

They are I/O intensive and as such, do not benefit from a multicore CPU. —Preceding unsigned comment added by 77.70.95.214 (talk) 19:32, 8 February 2008 (UTC)[reply]

Multi-core versus Multicore

This may be a non-issue, but it seems that multicore is becoming the more popular spelling for multi-core/CMP machines. 68.34.101.214 (talk) 15:01, 22 March 2008 (UTC)[reply]

Jargon and encyclopedias

Given that this is supposed to be an encyclopedia for non-initiates to find info on various topics, is possible to keep the jargon to a minimum? I was interested in knowing precisely what dual core processors were, but I found little that was comprehensible on this particular page. A one-paragraph, jargon-free definition could perhaps be added at the top of this article. Thanks! Episteme1972

ps3?

You mention the xbox, doesn't the ps3 have more?

It does. Xenon has 3 cores, Cell have 9. -- Henriok (talk) 13:19, 18 June 2008 (UTC)[reply]

The cell has seven cores, and they are actually SPEs, not cores. It would be more accurately to remove the playstation 3 as an example of multi-core because it is atypical. --Colostomyexplosion (talk) 14:01, 31 July 2008 (UTC)[reply]

The Cell has 9 cores, and even though it is atypical, it's still 9 cores. Even if the Cell in PS3 have one disabled in manufacturing and one out of bounds for homebew, it's still 9 cores. The eight SPEs have their own pipeline, local memory, registers and ISA. They are cores and because it's atypical it'd be a nice example here. -- Henriok (talk) 21:16, 21 August 2008 (UTC)[reply]

Commercial examples - cleanup

I'm going to attempt to clean up the commercial examples section, but there are a lot of dubious entries in there. Firstly, is a general purpose microprocessor and a DSP on the same die a multicore processor? I don't believe so, and I will remove them if there are no objections. Secondly, do we need to list every single embedded multicore processor in existence? Since they are more common than hydrogen atoms, I suggest that only those with proven notability (eg. novel design - hundreds of cores, significant market presence, exceptional application) should be included, since a lot of the entries sound like advertisements to me. Thirdly, I think there should be some brief info for each entry on why the processor is notable. What do you think? Rilak (talk) 05:55, 5 June 2008 (UTC)[reply]

Sound good. I agree -- Henriok (talk) 13:27, 18 June 2008 (UTC)[reply]

If you look at the edit history, I've already started and have removed a few entries. I'll try and get the list coherently ordered soon. Does ordering the entries alphabetically and maintaining a coherent format (eg. MyCorp MyCores, a 24-core MIPS processor) sound good to you? Rilak (talk) 05:54, 19 June 2008 (UTC)[reply]

I've deleted a few entries such as the Diopsis, as it seems to be a DSP and a CPU stuck on the same die, and the Infineon IP phone processor, as it seems to be a DSP stuck with something else (microcontroller?). I've also begun sorting the entries in alphabetical order, with the name of the company first, followed by the name of the product. It would also be helpful it someone updated the AMD and Intel entries, some of the information seems a bit old. Rilak (talk) 10:23, 22 June 2008 (UTC)[reply]

The cleanup is complete. A few entries got axed, primarily the Freescale PowerPC softcores. I do not feel that these are actual "examples" as they are generally ordered by customers to integrate into their own products. Also axed were entries that did not describe any actual "examples", but companies/people that design/fab multicore processors as part of their business. Unless actual examples are provided, I think that such entries should not be included as they are too vague. Finally, the software examples section looks like that it is infested with advertising. Most of the links are external, suggesting that the entries are there to promote a product rather than to describe one. If they are indeed notable, they should link to a Wikipedia article. I'm not knowledgeable about this subject, so I won't remove any content, but I think that a cleanup of the section is warranted. Rilak (talk) 12:08, 28 June 2008 (UTC)[reply]

Core?

What is a core? The fist mentioning of the word "core" is on the first line in this article and it points to a disambiguation page, core. This is not good. There should be an article describing a processor core, and it should not redirect to this article. -- Henriok (talk) 13:31, 18 June 2008 (UTC)[reply]

I agree. The disambiguation for "core" does not define what it is. Rilak (talk) 05:56, 19 June 2008 (UTC)[reply]

page is a little too PC centric

the page isn't objective and isn't platform neutral, and it gives almost no technical insight besides being a advertisement for users how great multi-core is, and then pointing out negatives which aren't actually negative for multi-core systems. Markthemac (talk) 20:35, 14 July 2008 (UTC)[reply]

Could you point out what is exactly wrong with the article? Specific paragraphs, sentences, statements, that sort of thing? Rilak (talk) 07:39, 15 July 2008 (UTC)[reply]

point:1 In order to continue delivering regular performance improvements for general-purpose processors, manufacturers such as Intel and AMD have turned to multi-core designs, sacrificing lower manufacturing costs for higher performance in some applications and systems. 2

for example the American PC game developer Valve Corporation has stated that it will use multi core optimizations for the next version of its Source engine, shipped with Half-Life 2: Episode Two, the next installment of its Half-Life series.[2][3], and Crytek is developing similar technologies for CryEngine 2, which powers their game, Crysis. Emergent Game Technologies' Gamebryo engine includes their Floodgate technology[4] which simplifies multicore development across game platforms. See Dynamic Acceleration Technology for the Santa Rosa platform for an example of a technique to improve single-thread performance on dual-core processors.

and i think u can read more yourself, games etc are really only interesting for gamers and not developers or anyone really interested in multi-core development and reasons behind certain processes. Markthemac (talk)

Out of the entire article, I only found one paragraph, the one you quoted, that deals specifically with computer games. I don't see how this makes the article bias in any way, especially when there is an entire section, approximately one and a half pages long that deals with development and software on multicore processors and licencing for high-end data center and technical applications. The paragraph which you claim is bias has full justification for being in this article - computer games have a major role driving the development of hardware, and it has been doing so since the late 1990s. If the article ignored the application of multicore to consumer and entertainment systems (all modern video game console processors - Broadway, Cell, Xenon are multicore), then the article would be truly biased and misleading as it is promoting a one sided view of the concept.
